WALKING-BEAM MOUNTING.

Application led- December 6, 1925. Seriall No. 153,029.

and easily installed and rigidly supported.

A still further object is to provide a supporting post mounted and supported in a simple and efficient manner.

Another object of' the invention is to-'provide a brace foot member adjustable with relation to the base offv the postI for taking up slack and play.

*n construction designed to carry out the invention will be hereinafter described, together with other features ofl the invention.

he invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Fig. 1 is a. side eleva-tion of a walking beam mounting constructed in accorda/nce with my invention,

Fig. 2 is a vertical sectional view of the Samson post,

Fig. 3 is a cross-sectional view taken on the. line 3:-3 of Fig. 1:, Y

Fig. et is a plan viewV of the front brace footing.

In thek drawings the numeraldesignatesv an upright Samson post, which is preferably formed of pipe cut to the proper length, but which may assumeA any shape consistent with the invention. This post is seated inan annular recess or socket11 and surroundedy by an upstanding annular. flange 12 integral with a base plate 13. The base' plate.` is fastened by foot bolts 14: imbedded iny a concrete. basey 15 on which the plate. is supported.

At the upper end of thet post 10 I mount saddle plates 1'6 which have their inn-er sides curved to conform. to the contour of the'post. These plates are4 mounted. on opposite sides of the post and are secured thereto by bolts 17. Each plate is provided with` an inwardlly directed shoulder 1'8 resting ontop et the post and taking the downward thrust oifioff the bolts- Above its shoulder, each` plate" 16 has` a concaved bearing saddle 19` for re-y ceivino; tlf-,c transverse fulcrum bar 20 of av walking beam 21. The walking beamis preferably formed of metal members, but its particular construction is not a part of the invention. Each plate 16 is provided? with central vertical ears 22 receiving the 1 eyes of inclined brace rods 23. These brace rods may be omitted' ifdesired. l

Gne of the features of the invention resides in bracemembers applied to the* front and rear and one 'side of the Samson post. ALs each of these braces is substantially the' same in construction, I have designated themby thev letters A, B and C andil have applied to like parts the same reference numerals; Each brace includes an upper bracket 24 curved to fit the contour ofthe; post 10 and provided with vertical side flanges 25 se#v cured to the post by bolts 26. 'Ihe` bracket includes an angular boss'27 having a lug 28V extending" Voutwardly from its lower end. When lthe bracket is mounted: on the Samson. post, the lower face inolines upwardly at' an angle tothe post.. In the bottom. of the boss I provide' a circular socket. 29",' as is shown in Fig. 2. f

The brace member constitutes a tubular brace or pipe having its upper end seated in the socket 29 and a tension rod 31.. eX- tending through the lug 28" and receiving' a nut 32 on its upper end. At the lower end of the brace member, I provide a foot member 33, including" a horizontal base plate 34 mounted on a sill plate 35 and an upwardly extending boss 36. he boss is provided with a circular socket 37 receiving the lower end of the brace 30, and is also undercut to form a lug 38 through which the rod 31.k passes.' A. nut 39 is screw-threadedL on" the lower end of the rodl and by tightening the nuts Band 39 the brace 30 is seated' in its Y sockets, whereby the brace member is -tenassembling the brace member, the base 34 Vis slidable on the sill plate 35. In carrying out this `part'of the construction, the sill plate is held in position by foot bolts 40 imbedded in the concrete base 15 and extending up through slots 41 in the plate 34. Nuts 42 mounted on the upper .ends of said bolts serve to confine the base'plate on the sill plate and to fasten the base Aplate in position. Y To adjust the foot member, a tie rod 43 is provided at its inner end with an eye 44 engaged over one of the foot bolts 14 of the Samson post base plate 13. The other end 0f the rod extends through the boss 36 and is screw-threaded to receive a nut 45, which bears against the outer end of the foot member. It will be seen that by loosening the nuts 42 and turning the nut 45 to the left, or removing it if necessary, the foot member can be slid outwardly so that the brace 30 may be stepped into itssockets. Then by replacing the. nut 45 and `screwing it to the right, or in a clockwise direction, the foot member will be slid inwardly on the plate 35, thus taking up the slack in the brace. The nuts 32 and 39 are, of course, tightened and by properly adjusting the nuts 32, 39, 42 and 45, the brace member may be rigidly y positioned and the Samson post firmly held in place. i

The brace members A and Bbeing in line with the walking beam 21, will `brace the Samson post against tilting back and forth 2in the arc of the swing of said beam. lIhe side 'brace member C will also act as a strut, whereby the post will be braced against tilting to either side. Where therods 23 are employed, they will, of course, act as additional side braces, and, if necessary, a brace rod 46, including turn-buckle 47, may have its upper end secured to a stud 48 on the side of the Samson post. The lower end of the rod 46 is provided with a head 49 engaged in a housed ear 50 on the base plate 13. The rod 46 is placed on the opposite Side4 from the brace I/Vhen the beam 21 is not in use, it is customary to provide a'support for the same,

wand, therefore, an upright post 51, known in the oil fields as a headache post, is mounted on a `flanged base 52, which is secured to the concrete base 15 Vby foot bolts 53. Side braces 54 may be employed if de- T sired. The upper end of the post 51 is held in place by a reach rod 55 secured to the, Samson-post. y

It is to be understood that any type of walkingbeam may be mounted in bearing saddles 19. In constructing the parts 10, 30'and 51, what is known as junk pipe or'tubing may be used, therefore, making for economical construction;`

Various changes in the size and shape of thefdifl'erent parts, las well as modifications vmounted on the base, saddle plates secured to the upper end of the post, brace brackets fastened to the upper portion of the post on its front and rear sides, a rear brace inclined fromthe rear bracket, a rear foot member receivingthe lower end of the rear brace, a front brace inclined from the fro-nt bracket, a front foot member receiving the lower end of the front brace, a tie rod eX- tending from the post base member to the front foot member, and tie rods extending from the brackets down the brace and secured at their lower ends to the front and rearfoot members.

4. In a walking beam mounting, the combination of a Samson post, a bracket secured to the post at its upper portion having a socket and a lug, a foot member spaced from the base of the post and having a socket and a lug, a brace member having its upper and-lower ends seated in the sockets of the bracket and the foot member, a tie rod eX- tending parallel to the brace having its ends engaging in the lugs, means for tensioning the tie rod to fasten the brace, and a second tie rod extending from the post base to they
